Always inspect harness connectors that are involved in the
circuit. Poor connections can often be the cause of an electrical
circuit problem. Verify that all connections in circuit are clean and
secure, and connections are in good condition. If a problem with
a connection is found, correct problem and verify diagnostic code
is active before performing this procedure.
Tag wiring harnesses to aid installation.
